Attention & Flow¶

Your focus is the raw material of learning. How you manage it — and the state you study in — matters as much as the techniques.

Single-tasking and "attention residue"¶

When you switch tasks before finishing the first one, part of your mind stays stuck on it — attention residue (Leroy, 2009) — and it degrades your performance on the next task. The driver is incompleteness: an unfinished task keeps tugging.

Implications:

Study in single-focus, completed blocks. Don't bounce between tasks mid-thought.
Multitasking is a tax, not a skill. Every switch leaves residue. Doing two demanding things "at once" means doing both worse.
Reach a sense of closure before switching — even "I'll finish this later at a set time" reduces the residue.

Flow vs. Deliberate Practice — use the right one¶

Flow (Csikszentmihalyi) is the smooth, absorbed state where you perform at your best. But here's the key insight: flow is a performing state, not a learning state. Deliberate practice is effortful strain at the edge of ability — the opposite of smooth.

So separate them:

Learning/studying → embrace the effortful, error-filled strain. Don't expect or chase flow here.
Performing/executing → aim for flow: pick challenges where your skill slightly exceeds the difficulty (both elevated), so you're engaged but in control.

Difficulty calibration needs more than difficulty¶

Modern research finds challenge-skill balance alone isn't enough to produce flow or good engagement — you also need clear goals and a sense of control. So when you set up a session:

Pitch the difficulty so you feel slightly favored but stretched.
Set one concrete goal for the session.
Make sure you feel agency over your choices.

Try this

Before each session, write one sentence: "This session I'm working on , and I'll know it went well if ." Then close every other tab/app. Clear goal + single focus = the conditions for both learning and flow.

In poker

Table count is an attention budget — each unresolved table taxes the others (attention residue), so cut tables when a spot isn't autopilot. And use the two states deliberately: strain to study, flow to play (pick games where you feel slightly favored but engaged). → Build Your Routine

Key takeaway¶

Protect attention ruthlessly: one task, finished, at a time. Use strain for learning and flow for performing — and never confuse the two.
